Data Sharing
NOTE: This feature is not available in NCache Express and Professional edition.
NCache is providing both .net and java clients and there is a possibility of sharing same cache data among various clients either from same or different platforms. To make this sharing possible NCache has designed Data Sharing feature which not only allows the users to share cache content between various platforms but also provides the facility of class versioning within a same platform. Data sharing is a technique which dynamically serializes the objects at run time and makes it available for use in a very efficient way (in terms of time and cost).
Data sharing also supports class versioning as discussed above. Class can have various versions associated with it having unique identifiers. Every new change in a class is saved as a new version of the class. Through Data Sharing, different class versions can share cache contents among them at run time.
Data sharing is defined as the process of converting the state of an object (of any type) to some persistent state so that it can be understandable by clients from different platforms. This is the process which allows user to dynamically serialize an object to make it portable for different platforms/versions. In this way user can make persistent data state, so that it can be saved on a remote location and can be easily accessible for all clients.
The most common methods available in market for data sharing are XML based which is comparatively a slower solution. NCache introduces an efficient technique for Data Sharing that is binary serialization of objects at runtime.
Data Sharing is a very magnificent feature for all those clients who are using both NCache .net and NCache java editions but have some limitation as listed below:
The following mapping should be considered while serializing a .Net/Java class:
Note: Users should only map Java attributes to .Net attributes incase of unsigned types.
